-Subject: [PATCH] ppp: use the buffer stack for the de-escaping buffer.
-
-This both saves the buffer for freeing later and saves the packet
-pointer and snapend to be restored when packet processing is complete,
-even if an exception is thrown with longjmp.
-
-This means that the hex/ASCII printing in pretty_print_packet()
-processes the packet data as captured or read from the savefile, rather
-than as modified by the PPP printer, so that the bounds checking is
-correct.
-
-That fixes CVE-2024-2397, which was caused by an exception being thrown
-by the hex/ASCII printer (which should only happen if those routines are
-called by a packet printer, not if they're called for the -X/-x/-A
-flag), which jumps back to the setjmp() that surrounds the packet
-printer. Hilarity^Winfinite looping ensues.
-
-Also, restore ndo->ndo_packetp before calling the hex/ASCII printing
-routine, in case nd_pop_all_packet_info() didn't restore it.
-
-Upstream-Status: Backport [https://github.com/the-tcpdump-group/tcpdump/commit/b9811ef5bb1b7d45a90e042f81f3aaf233c8bcb2]
